We attend the team camp, I do believe that those who attend the technique camp get randomly placed on a team for the duals in the afternoon. I will say the technique session is awesome. They have about 10 mats going all with different techniques, which makes it nice for the coaches and wrestlers to choose what they want to work on.
Coach Henson and OU wrestlers do an excellent job of breaking down the techniques and insuring the wrestlers are absorbing the lessons.
